CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/050,026 filed Jul. 31, 2018 and titled “SYSTEM AND METHOD FOR COUPLING A USER COMPUTING DEVICE AND A POINT OF SALE DEVICE”, which is a continuation of U.S. application Ser. No. 14/098,318 filed Dec. 5, 2013, now U.S. Pat. No. 10,068,276 and titled “SYSTEM AND METHOD FOR COUPLING A MOBILE DEVICE AND POINT OF SALE DEVICE TO TRANSMIT MOBILE SHOPPING CART AND PROVIDE SHOPPING RECOMMENDATIONS,” all of which are incorporated herein by reference in their entirety

BACKGROUND

A busy shopper may have a large number of items to pick up. Upon arrival at a point of sale many customers have had the unpleasant experience of realizing that a needed item is not in the customer's cart or was not purchased during a weekly shopping trip. Remedying this situation is inconvenient for all. A cashier may simply wait while the customer goes to retrieve the item. This increases the time the customer requires to checkout. Other customers in line may b ecome particularly frustrated if made to wait. The cashier might simply conclude the transaction for the retrieved items, requiring the customer to retrieve the item and then wait in line again to purchase the unretrieved item. This creates additional inconvenience inasmuch as the purchase of previously purchased items may need to be verified by the cashier when processing payment for the previously unretrieved item. A customer may be further inconvenienced by arriving home only to realize that a needed item was not purchased.

The systems and methods described herein provide an improved approach for assisting a customer in purchasing needed items.

FIG. 3A illustrates an interface 300 that may be presented on a user computing device 104, such as a user computing device 104 embodied as a mobile phone or tablet computer. The interface 300 may include an interface element 302 for receiving search terms and invoking a search of a product database, such as a product database hosted by a server system 102 a, 102 b. An “I need” interface element 304 may invoke functionality according to the methods described herein for providing a recommendations to a user. A “scan code” interface element 306 may invoke an interface and functionality enabling a user to scan a UPC, QR, or other optical code affixed to or otherwise identifying a product. A “favorites” user interface element 308 may list a selection of frequently purchased products or products designated by a customer as a favorite. A “basket history” interface element 310 may invoke display of items recently purchased by a customer. In addition to the functionality represented by the interface 300, the methods disclosed herein for providing recommendations may generate listings of products that may be used by a user to invoke any ecommerce method or provision of enhanced information or functionality known in the art with respect to a product in the listing.

FIG. 3B illustrates a recommendation interface 312 that may be displayed in response to user selection of the “I need” interface element 304. Alternatively or additionally, as shown by the “add item” interface element 314, the interface 312 may be displayed in response to user selection of an interface element in any other interface that may be used to add an item to an electronic shopping list, such as a browser for searching and adding products to a shopping list or electronic shopping cart or other application or interface for viewing or selecting products.

The interface 312 may include a listing of products (Item A-Item D) identified and ordered according to the methods described herein. A listing of products may be too long to display all at the same time. Accordingly, the interface 312 may include interface elements enabling a user to invoke scrolling through the listing of products.

A first portion of the elements of the listing may include validation indicators 316. A second portion of the elements of the listing may include alternative indicators 318. The validation indicators 316 indicate that the product marked with a validation indicator 316 is a good choice among possible alternatives based on some criteria, such as price, nutritional value, calories, or the like. An alternative indicator 308 may indicate that the product with which it is associated is not the best choice among possible alternatives based on the same or different criteria. By selecting one of the alternative indicators 318 and the element (e.g. “Item C”) with which it is associated, a user may invoke display of the better alternatives, which may include a comparison showing the original element as well as one or more alternatives and the values for the one or more criteria.

The recommendation interface 312 may further include interface elements 320-326 for invoking one or more other functions to facilitate a user's shopping. For example, interface element 320 may invoke display of an interface for displaying and modifying a shopping list. Element 322 may invoke display of an interface for displaying and modifying an electronic shopping cart. Element 324 may invoke display of an interface for browsing a product catalog or performing other product related “shopping” activities. Element 326 may invoke display of an interface for locating nearby stores.

FIG. 4 illustrates a method 400 for characterizing a customer's transactions to facilitate processing according to the methods disclosed herein. The method 400 may be executed by a server system 102 a, 102 b. Some or all of the processing for implementing the method 400 may also be performed on a user computing device 104. The method 400 may include detecting 402 customer purchases. Purchases may be reported by a POS 106 to a server system 102 a, 102 b. Purchases may be associated with a particular consumer by the consumer reporting a consumer identifier to the POS 106 at the time a transaction is concluded. This customer identifier may be associated with a report of the transaction reported to the server system 102 a and the server system 102 a may store a report of the transaction, or some or all of the information therein, in association with that customer, such as by means of the same or a different customer identifier. Alternatively or additionally, reports of customer purchases may be reported by the customer. For example, the customer could enter purchases into an interface that submits a report of such purchases with a customer identifier to the server system 102 a. Alternatively or additionally, reports of the consumer identifier may be transmitted to a POS 106 by a mobile device 104 with contents of an electronic shopping cart as part of a mobile self checkout routine whereby the user assembles an electronic shopping cart with items, the device 104 is paired with the POS 106, and the device 104 transmits the shopping cart to the POS 106 for concluding the transaction. The customer identifier may be transmitted to the POS 106 for association with a transaction as part of other types of transactions.

The method 400 may further include evaluating customer transactions in order to determine amounts of products purchased and when. In particular, product A may be represented among transactions. The user may have purchases 10 units of product A, then purchase 15 units three weeks later, and then purchase 5 units five weeks after that. Using this information, the method 400 may include determining 406 a consumption rate. For example, using the above example, the consumer may be determined to consume 10 units of product A every month. In general, a consumption rate may be determined by the ratio P/W, here P is the number of products purchased in a time window and W is the length of the window.

The method 400 may further include determining a shopping trip frequency based on the detected transactions, e.g. the average time elapsed between transactions. The method may further include predicting 408 a next shopping trip for the customer based on the shopping trip frequency. In some embodiments, the methods disclosed herein may be performed while the customer is in a store or otherwise in the process of going shopping on the day the methods are performed. Accordingly, predicting the next shopping trip may include predicting a next shopping trip after the current day on which the methods disclosed herein are executed, taking into account that the current day is a shopping trip. Predicting when the next shopping trip will be may include adding the shopping trip period to the current date (e.g. if the frequency is every N days, add N days to the current date to fine the predicted next shopping trip).

FIG. 5 illustrates a method 500 for providing product recommendations. The method 500 may be performed using data generated according to the method 400. The method 500 may include evaluating 502 a customer's most recent purchases 502 of a plurality of products and evaluating 504 a consumption rate of the customer for those products. Based on the evaluations 502, 504, the method 504 may include determining 506 a runout date. For example, where X is the most recently purchased amount of product A and R is a consumption rate (units of product per unit time), the runout date may therefore be A/R after the date of the most recent purchase of product A. Other algorithms may also be used.

The method 500 may further include prioritizing 508 products according to runout dates. For example, products with the soonest predicted runout date may be given higher priority. In some embodiments, prioritizing 508 may include filtering products using a predicted date for a next shopping trip. For example, those products that have runout dates after a next shopping trip may be omitted. In particular, where the method 400 is executed in preparation for a current shopping trip and the predicted shopping trip date is for a next shopping trip subsequent to the current shopping trip. Products that are rarely purchased or for which no pattern of repeated purchase is found may also be omitted from the prioritizing.

The method 500 may further include identifying valid products from among the plurality of products. Valid products may include products that meet one or more criteria, or are better than alternatives with respect to the one or more criteria. For example, a valid product may be a product that has the lowest per unit cost than alternative products, e.g., the cheapest per ounce, gram, piece, or the like. Alternatively, a criteria may relate to quality, such as according to a ranking by a publication, rankings by users who have reviewed the product, or some other metric. In yet another alternative, a score may be assigned to a product based on a plurality of such criteria (e.g. sum, weighted sum, product, weighted product, or some other combination), and a valid product may be one that has the highest score among a group of alternative products. In some embodiments, rather than being the highest rated according to a criteria or combination of criteria, a valid product may be one of the top N products according to a criteria or combination of criteria or meet a threshold condition with respect to a criteria or combination of criteria. Products found to be valid may be marked with a validity indicator 316 as shown in FIG. 3B when a listing of products is displayed to a user. Accordingly, a listing transmitted to a user device 104 may have an indication of validity associated therewith.

The method 500 may further include identifying 512 alternative products. In particular, where a product is found not to be valid, one or more alternative products may be identified. In some instances, no alternative, or clearly superior alternative, may be found. However, if a superior alternative exists, such as according to a criteria or combination of criteria as discussed above, one or more of such superior alternatives may be identified. If an alternative is found for a product, then an indication of an alternative may be associated with that product in a listing of products sent to a user device and used to display an alternative indicator 318 with a reference to the at product. The identified one or more alternatives may also be transmitted with the listing or transmitted in response to a user interaction with the alternative indicator 318 or a representation of the product with which it is associated. An alternative product may be transmitted as an identifier for the alternative product as well as values for the criteria or combination of criteria used to determine that the alternative product is superior.

The method 500 may further include presenting 514 a recommendation list including a listing of the products as ordered according to the prioritization as well as any validation or alternative indicators. Presenting the listing may include transmitting sufficient information to the user device 104 to enable the user device to visually represent the listing and otherwise enable a user to navigate and interact with the listing, such as discussed above with respect to FIG. 3B.

FIG. 6 illustrates a method 600 for using a listing of products as generated according to the method 500 to invoke other functionality to facilitate shopping by a customer. The method 600 may be executed on a server system 102 a with an interface provided on a user device 104 and some or all of the processing may also occur on the user device 104.

The method 600 may include receiving 602 user interaction with an item of a list displayed on the user device, the list including items that have been one or more of selected, prioritized, and marked with indicators according to methods disclosed herein.

The method 600 may include presenting 604 one or more alternatives, if any associated with the selected item. A user may then select one of these alternatives to add the alternative to a shopping list, shopping cart, or otherwise obtain information or begin a process of purchasing or locating the alternative. As noted above, presenting 604 alternatives may include presenting values for criteria used to select the alternative or that otherwise indicate the superiority of the alternative to an item of the list.

The method 600 may further include adding 606 the list item to a shopping list in response to an instruction from a user received on the user device. The shopping list may be an electronic shopping list and may be displayable in an interface for invoking one or more actions with respect to the shopping list. For example, the method 600 may include providing 608 directions to a list item such as by calculating a route through a store with respect to a shopping list. The method 600 may include adding 610 the list item to a shopping cart of items to be purchased. This may include adding 610 the list item to an electronic shopping cart in response to a user scanning a code affixed or otherwise associated with an instance of the list item. Adding 610 the item to the list may also be performed as part of adding an entire shopping list to the electronic shopping cart in response to an instruction from a user.

The method 600 may further include performing 612 checkout for the list item using the user computing device. Performing 612 checkout may include performing checkout with respect to an electronic shopping cart including the list item. Performing 612 checkout may include performing mobile self checkout in cooperation with a POS 106. For example, a POS 106 may receive a request to use mobile self checkout (MSCO). This may be communicated verbally to a cashier who then inputs or otherwise specifies the MSCO option to the POS 106. In response to receipt of this instruction, the POS 106, may generate and display a code that is used to couple a particular user computing device 104 to that POS 106. The displayed code may be a one-off code that is generated for each transaction or otherwise used for only one transaction.

The user computing device 104 scans the displayed coupling code. The user computing device then transmits the contents of the electronic cart to the POS 106 using the coupling code. This coupling code may be an address that can be used to transmit the contents of the electronic shopping cart directly to the POS 106. Alternatively, the contents of the cart with the coupling code may be transmitted with the coupling code to a server system 102 a, 102 b. The server system 102 a, 102 b may then interpret the coupling code to identify the POS 106 that generated the coupling code and transmit the contents of the electronic shopping cart to this POS 106.

The contents of the electronic shopping cart received by the POS 106 a may then be used to conclude 814 the transaction on the POS 106 a. The items received by the POS 106 may, for example, may treated in the same manner as items input to the POS 106 by scanning bar codes in the conventional manner. Likewise, concluding the transaction may include receiving tender of cash, check, or electronic payment, as for the typical in-store transaction. Other methods known in the art for concluding a transaction for an electronic shopping cart input to a user computing device 104 may also be performed. Likewise, items may simply be added to a physical shopping cart. A user may check off items from a shopping list as they are added to the physical shopping cart. A transaction to purchase the items may be concluded at a POS 106 in the conventional manner.

The invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative, and not restrictive.
